Investigation of Polylactic Acid Nanofibers as Enhanced Plant Growth Medium by Improved Melt-Blowing Method

Abstract:

An improved melt-blowing method have developed to manufacture the organic nonwoven nanofibers through our previous study. As a parallel phase, this study explores the potential of polylactic acid (PLA) nanofibers as a plant growth substrate, emphasizing the unique properties and performance when mixed with pellets. Preliminary experiments comparing different fiber materials, cultivated crops, and fiber diameters demonstrate the favorable characteristics of PLA, such as wettability and growth promotion. Comparative experiment with rockwool, a commonly used medium, shows that PLA nanofibers exhibit superior growth performance. On the other hand, a solidified PLA medium is produced and tested. Hydroponic tests using solidified medium configurations with varying fiber diameters and soil conditioners further confirm the benefits of PLA as a medium for plant growth. The findings suggest that PLA nanofibers have the potential to revolutionize cultivation practices, providing sustainable and environmentally friendly alternatives to traditional substrates.
